-## BEFORE YOU BEGIN
-I have attempted the following troubleshooting suggestions:
- [ ] The issue persists when using Firefox in [Troubleshoot Mode](https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode).
- [ ] Disabled DNS-level content blocking (AdGuard Home, NextDNS, Control D, RethinkDNS, PiHole, etc), [cleared my DNS cache](https://www.pcmag.com/how-to/how-to-flush-your-dns-cache), and used my ISP's DNS resolver (if applicable).
- [ ] [Cleared website data](https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox), restarted Firefox, and my issue persists.
- [ ] I have created a [new profile](https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles). The issue persists when using the current [user.js](https://github.com/yokoffing/Betterfox/blob/master/user.js) file on GitHub. (Must be in a new profile and a new user.js!)

-// loads pages faster because the network can be quicker than accessing the cache
-// on a hard drive. When RCWN is enabled, the request might be served from
-// the server even if you have valid entry in the cache. Set to false if your
-// intention is to increase cache usage and reduce network usage.

+
+Usage:
+    python install.py
+    
+
+When called without arguments, it will:
+- Backup your current firefox profile
+- Automatically download user.js from the latest Betterfox release compatible with your Firefox version into the profile
+- Apply user-overrides in the same directory 
+
+However, you can check out install.py/betterfox-install.exe --help to customise most behaviours!
+
+Limitations:
+- When using a different repositoy as a source, that repository needs to use the same releases workflow
+- Over time, the get_releases might not list older releases due to limited page size. This can be expanded down the road, though
+
+Building into an exe (on Windows):
+- pipx install pyinstaller  (note: you can try without pipx, but this didn't work for me)
+- Run:
+  - CMD:  `pyinstaller --onefile --name install-betterfox install.py && move %cd%\\dist\\install-betterfox.exe %cd% && del install-betterfox.spec && rmdir /S /Q build && rmdir dist`
+  - BASH: `pyinstaller --onefile --name install-betterfox install.py && && mv dist/install-betterfox.exe . && rm install-betterfox.spec && rm -rf ./build/ && rmdir dist`
+  (Sorry, didn't want to add a .gitignore solely for the install script)
+- Done!
+
+If there's any problems with the script, feel free to mention @Denperidge on GitHub!

+#### A user.js for Waterfox
+Just FYI: There are some long-term issues with Waterfox where the browser doesn't load certain internal settings or resets prefs after restart. For examples, see https://github.com/BrowserWorks/waterfox/issues/3196 and https://github.com/BrowserWorks/waterfox/issues/3947.

+> Fork-specific files are side projects and will not update every release. When in doubt, use the standard Firefox user.js.
